We began in 2016 with a single rooftop installation and a notebook full of questions. What started as a side project to document collector performance in Rajasthan's dusty summers grew into a community-driven review platform. Today, our team of five field engineers and former plumbers compiles installation feedback, maintenance logs, and efficiency data from households across India, so you can choose a solar thermal system with confidence.
SolarSiphon started as a small group of solar thermal technicians and homeowners who were tired of vague product claims. We began documenting real installation outcomes, maintenance logs, and seasonal performance data from Indian rooftops. Today the team includes engineers, field assessors, and customer support staff who verify every review before it goes live.
Read our full storyRoma spent six years servicing evacuated tube systems across Tamil Nadu. She now trains local installers on proper collector angling and tank insulation, and she personally audits the highest-rated installations before they appear on the platform.
Wafiq compiles the seasonal performance charts and compares user-reported hot water output against manufacturer datasheets. His background is in mechanical engineering with a focus on heat transfer in flat plate collectors.
Heena contacts every reviewer by phone to confirm the installation date, system capacity, and the specific issue they described. Her checks keep the review database free of duplicate or sponsored entries.
Supriya documents warranty claim experiences and tracks how manufacturers respond to tank leaks, failed electric backup elements, and collector glass damage. Her summaries help buyers compare after-sales support before purchase.
Bhola organises maintenance workshops in Pilani and nearby towns, teaching residents how to flush tanks, check pressure valves, and spot early signs of sediment buildup. He also collects feedback from small businesses like hostels and guesthouses.
Every submission passes through a two-step review: an automated check for duplicate serial numbers and a manual read for clarity. Only verified installations with a confirmed address and purchase date are published.
SolarSiphon started with a simple observation: households across India were buying solar water heaters without reliable feedback from people who actually used them. We wanted to change that.
Every review on this platform comes from a verified installation, not a marketing team. We collect feedback from homeowners, landlords, and small business owners who have lived with their systems through at least one full season. That means you read about real performance during summer heat, monsoon cloud cover, and winter mornings, not just the brochure numbers.
You get the unedited picture before you commit to a purchase.A solar water heater that works well in Jaipur may struggle in Shillong. That is why we ask reviewers to describe their location, roof orientation, water hardness, and daily hot water demand. These details matter more than brand names. Our job is to preserve that context so you can find feedback that matches your own situation.
Advice stays grounded in the conditions you actually face.Technicians, plumbers, and experienced users contribute as much as homeowners. Their maintenance tips, troubleshooting notes, and warranty claim stories fill the gaps that product manuals ignore. When someone shares how they fixed a pressure issue or dealt with a leaking valve, that knowledge stays available for the next person.
Your experience becomes a resource for someone else's decision.We do not rank brands for the sake of ranking. Instead, we compare collector types, tank capacities, and installation practices side by side, using the data reviewers provide. You can see how evacuated tube systems perform against flat plate collectors in the same city, or how different tank sizes affect backup heating costs.
You weigh trade-offs with numbers, not guesswork.
